      A function that calculates the MD5 hash of a file.
  
      Args:
      -----
          filename: Path to the file.
          block_size: Chunks of suitable size. Block size directly depends on
              the block size of your filesystem to avoid performances issues.
              Blocks of 4096 octets (Default NTFS).
          binary: A boolean representing whether the returned info is in binary
              format or not.
  
      Returns:
      --------
          string: The  MD5 hash of the file.
